NSIDC at AGU

If NSIDC scientists are busy all year long conducting their own research, how do they keep up with what their colleagues elsewhere are doing? They exchange flurries of emails and phone calls, of course, and collaborate on journal articles and projects. But once a year, many of them are in the same place at the same time for the same reason: to attend the fall meeting of the American Geophysical Union (AGU). Whether you’re interested in glaciers or geoids, sea ice or plate tectonics, Earth or Mars, AGU is right up your alley. Each year, more than 20,000 scientists, students, and educators converge in San Francisco for the weeklong meeting. Many of NSIDC’s staff participate in the meeting as well, presenting talks and posters detailing their latest research, data, and success stories.

Collaboration and the cryosphere

The meeting turns out to be a great place to run into normally-distant colleagues and discuss your research or hatch future collaborations. Scientists and project managers from around the globe also take advantage of AGU to coordinate with each other in person, saving the time and expense of setting up a separate meeting. Town Hall meetings provide government agencies, academic programs, and special projects with a forum to gather input from AGU attendees and convey information, which helps funding agencies set their priorities. NSIDC’s booth is also a big draw at the exhibit hall, where we feature some of our most recent and popular products. Talking with hundreds of meeting attendees helps us determine what kinds of data people are looking for, and how we can help them find what they need to conduct their research.

The variety of opportunities at AGU also fosters numerous informal meetings, whether we’re mingling between talks or at events like the Cryosphere Reception. This is often where new ideas can foment that would never come up in the more formal structure of science talks or project meetings. It is also a place to discuss better ways to improve understanding of science by students and the public and to communicate the latest science news at media briefings.

Among the cryosphere sessions, Greenland’s dramatic summer melt was a hot topic, as was sea ice, the effects of atmospheric carbon, and thawing permafrost. This year’s Nye lecture, one of the cryospheric highlights of the meeting, featured Elizabeth Morris of the Scott Polar Research Institute. Her talk, “Hot ice and wondrous strange snow: three-phase mixtures or something more?” delved into the process behind the science, how researchers study things in the field and then make that information useful in broader scientific contexts. The Nye lecture is just one of several plenary lectures that touch on a variety of disciplines, such as oceans, volcanism, and atmospheres.

Something for everyone

No matter what your discipline, AGU has something for everyone. Award-winning journalist Ira Flatow, host of National Public Radio’s “Talk of the Nation: Science Friday” program, spoke at the AGU presidential forum. He reminded all of us why science—and communicating that science clearly—is more important than ever. And the first annual AGU Open Mic Night: Tall Tales and Earth Sonnets, hosted by cryosphere expert Richard Alley, was a stratospheric success. If you didn’t get there early enough to get a chair, it was standing-room only.

Even when science is conducted in a vacuum, it’s never really conducted in a vacuum. The energy and synergy of ideas that occurs at AGU keeps us coming back. We’ll see you next year.

What is causing Arctic sea ice decline?

Readers sometimes ask us, “What are the reasons behind Arctic sea ice decline?” In summer months, ice extent has declined by more than 30 percent since the start of satellite observations in 1979. But is climate change really the culprit, or could other factors be contributing? Continue reading

Are icebreakers changing the climate?

On July 20, 2011, the U.S. Coast Guard Cutter Healy traveled through a break in the sea ice and melt ponds in the Arctic Ocean, during the NASA Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment (ICESCAPE) mission, a field survey aimed at understanding the ecology of the Arctic Ocean. |Credit: NASA/Kathryn Hansen|{a href=http://nsidc.org/icelights/files/2012/04/nasa_icebreaker.jpg}High Resolution Image{/a}

In summer months, icebreaking ships head north into the Arctic Ocean, tearing through the sea ice and leaving trails of open water in their wakes. Readers occasionally write in to ask us whether the trails left by these ships contribute to the melting of sea ice. Continue reading

The Arctic sea ice maximum

NSIDC scientists announced today that the Arctic sea ice cover has likely reached its maximum extent, marking the beginning of the melt season. (For details, see Arctic Sea Ice News & Analysis). What is the sea ice maximum and why does it matter?

The maximum ice extent marks the beginning of the melt season for Arctic sea ice. Leads, long cracks in the ice, begin to open up and the ice cover starts to melt as sunlight brings warmth to the Arctic. |Credit: Angelika Renner

What is the maximum and when does it happen?
Arctic sea ice melts and regrows in an annual cycle, freezing throughout the winter months and melting in the spring and summer. The ice cover generally reaches its maximum extent sometime in late February or March. After that, ice melts through the summer, hitting a low point in early or mid-September. NSIDC scientist Walt Meier said, “The maximum marks the point when the Arctic shifts from a freezing period into the summer melting period.” Continue reading

Modeling the Arctic climate

In February, polar climate researchers gathered at the National Center for Atmospheric Research in Boulder, Colorado to discuss the newest updates to models of the Earth’s climate system. The researchers are working together to create better models of the Arctic and Antarctic climates, which will feed into larger models of the whole Earth that help scientists understand how climate will change in the future. What goes into a climate model, and what can scientists learn from models that they cannot learn from observations?

What’s in a model?
Computer climate models are based on scientists’ understanding of Earth’s climate. The models use mathematical relationships to try to quantify the relationships between parts of the climate system. If you tweak one factor in climate, how does the simulated climate system respond? Models that bring many factors together help scientists learn how the climate system works, and let them run simulations on Earth’s climate. They also allow scientists to assess how climate may be affected by present and future changes in greenhouse gases and solar forcing, and how much of a role natural variability plays. Continue reading
